Exhaust treatment

In the chemical industry, where streams can be much more complex exhaust air treatment systems are provided that allow operation even in the presence of high concentrations of halogenated, sulphuric and phosphorus organic compounds.

The exhausted halogenated and sulphur compounds are usually treated with one or more stages of wet absorption (scrubbers) and with a quenching section.

Scrubber applications in the Inorganic chemical industry are dealing with the elimination of:

Hydrogenated halogens

Amines

Ammonia

NOx

Nitric acids

SOx

Sulphuric acids

Sulphides

Silanes

Siloxanes

Silicium oxide

Halogenic silica

Boron

Hydrogenated boron

Boracid

Carbondioxide

Phosphoric acids

Halogenated phosphor

Phosphoric oxides

Titanium oxide

Halogenated titanium

Phosgene

With the incineration of chlorine containing wastes or with reaction processes where hydrochloric acid is produced, exhaust gases with relatively large amounts of hydrogen chloride are generated which have to be separated. For the purpose of cleaning these exhaust gases a gas scrubbing plant offers the most economical solution.

The nonferrous and ferrous metallurgy is concerned with the extraction and processing of ores and the production of nonferrous / ferrous metals and their alloys. During these processes, by-products occur which include dust of metal oxides or mineral fertilizers and undesirable gaseous components which must be cleaned before released to the environment

GEA is one of the largest suppliers of process technology for the food industry and a wide range of other industries. The international technology group focuses on process technology and components for sophisticated production processes in various end-user markets.

In 2017, GEA generated consolidated revenues of about EUR 4.6 billion. The food and beverages sector, which is a long-term growth industry, accounted for around 70 percent.
